USING SUCH A COMPOSITION
The present invention relates to an oxidation dye composition for fibers keratin and in particular human keratin fibers, comprising in combination) at least one 3-fluoroparaaminophenol and at least one coupler of type metaaminophenol or metaphenylenediamine of formula (I) described below.
It is known to dye keratin fibers and in particular the hair humans) with dye compositions containing dye precursors oxidation, in particular ortho- or paraphenylenediamines, ortho- or paraaminophenols, generally called "oxidation bases", and couplers also called coloring modifiers, more particularly meta-phenylenediamines) metaaminophenols and metadiphenols, which allow to modify and enrich in reflections the "background" colors obtained by the condensation products of oxidation bases.
Nowadays) there is a strong craze for colorations with reflections copper, mahogany or red. Ju ~; that here, these shades were obtained with dyes with based of paraaminophenol associated with specific couplers. But currently, the use of par; ~ aminophenol is questioned for reasons toxicological.
The substitution of paraaminophenol is all the more problematic as for to be completely satisfactory, the dyes must also resist light to washes, bad weather, perspiration and various treatments what can undergo the hair.
To replace paraaminophenol, it has already been proposed to use 3-methylparaaminophenol as described in US Pat. No. 3,210,252. This product is nevertheless insufficiently soluble in dyeing media, generates a

2 recrystallization in the compositions, and ultimately does not make it possible to obtain the copper shades sought.
It is known, by; looters, according to French patent FR-1472078, to realize of oxidation tinctures with 3-fluoroparaaminophenol, but the nuances obtained are yellow and do not lead to copper, mahogany or red.
The plaintiff, after extensive research, has now discover, that by combining 3-fluoroparaaminophenol with couplers of formula (I) given in the following text, it is possible to obtain nuances to reflections coppery, mahogany or red, intense, meeting the resistance criteria evoked previously and this while avoiding ~ nt IAC nrnhlÄmce rcnnnn + ré ~. ~.

Concrete examples illustrating the invention will now be given. We will begin by defining the tests used to assess the performance of 2o oxidation dyes according to the invention in terms of their resistance to sweat, in light and shampoo.
Resistance to perspiration 25 A synthetic sweat solution of the following composition is used: 10 g from NaCI, 1 g potassium hydrogen phosphate, 0.25 g histidine, lactic acid up to pH = 3.2 ei: distilled water to make up to 100 g. In one crystallizer covered with a watch glass and containing this sweat solution, immerse them locks of dyed hair left to stand for 20 to 50 hours at 37 °
C. We 30 then rinse the wicks and dry them.

Light fastness (Xenotest) The dyed hair comes out fixed on a support (cardboard or plastic). These supports are arranged on sample holders which revolve around a Xenon lamp while a duration varying from 0 to 80 hours under a humidity level varying from 25 to 75%
RH (Relative Humidity;) and at a temperature of 25 ° C.
Shampoo resistance ~ Ahiba-Texomet machine) 1 o We place strands of dyed hair in a basket that we immerse in a solution of a standard shampoo. The basket is subjected to a movement of and-comes vertically with variable frequency as well as a rotational movement which reproduce the action of manual friction, which generates the formation of foam.
After 3 minutes of testing, the locks are removed which are rinsed and then dried. The tints can be subjected to several shampoo tests consecutive.
